<< 1. Outline of the light shielding device of the present disclosure >>
The light shielding device of the present disclosure makes it easy to see what should be concealed or invisible or in a visible state, depending on the condition near the light shielding wall. It is what makes it a state.

  More specifically, as shown in FIG. 1, the light shielding device of the present disclosure divides a first space on the left side in the drawing from a second space on the right side in the drawing, and shields light, transmits light, or It is comprised by the light-shielding wall 11 which consists of several panel 21 which can be controlled in the state changed into various transmittance | permeability. In order to simplify the description, the panel 21 is described as being switched to one of the two states, the light blocking state and the light transmitting state, for the purpose of simplifying the explanation. However, the panel 21 can also be controlled to various transmittances. Note that the light blocking state is a state in which the incident light is partially blocked, the transmission state is a state in which the incident light is partially transmitted, and the light blocking state is at least compared to the transmission state, It is sufficient if the transmittance of incident light is low. Therefore, for example, the transmittance of the panel 21 in the light shielding state may be at least lower than the transmittance of the panel state in the transmitting state, and the transmittance of the light shielding state may be 10% or 30% other than 0%. Well, the transmittance in the transmission state may be 90% or 70% other than 100%.

  The light shielding wall 11 controls, for example, only the panel 21 in the area where the object B1 present in the first space can be viewed directly from the viewpoint of the persons H1 and H2 present in the second space into the light shielding state. The panel 21 of the area is controlled to be in the transparent state. That is, the light shielding device of FIG. 1 is designed to make it difficult to show something that you do not want to show.

  More specifically, the light shielding device of FIG. 1 includes the light shielding wall 11, the cameras 12-1 and 12-2, and the control unit 13. The light shielding wall 11 divides a first space shown by the left part in the figure and a second space shown by the right part in the figure. As shown in FIG. 1, in the first space, there is an object B1 that you do not want to show to the persons H1 and H2 present in the second space (that you want to hide in the invisible state). On the other hand, in the second space, a person (for example, persons H1 and H2) can freely move.

  For example, as shown in FIG. 2, the light shielding wall 11 is configured of a plurality of panels 21. The panel 21 is, for example, a liquid crystal panel having a size of about 10 cm × 10 cm, and is controlled by the control unit 13 to be in the light shielding state or the transmission state. However, the transmission state includes states controlled to various transmission rates. The size of the panel 21 is not limited to about 10 cm × 10 cm, and may be smaller or larger than this size. Further, although an example in which the panel 21 is a square is shown in FIG. 2, the panel 21 may have a non-square shape or any other shape, and may be a polygon including a triangle, a circle, or Other geometric figures may be used. The panel 21 may have a configuration other than the liquid crystal panel as long as it can be controlled to either the light shielding state or the transmission state which can be controlled to various transmittances. Furthermore, one panel 21 may be divided into smaller areas and controlled to have different transmittances for each area, in other words, the panel 21 for the minimum unit for controlling the light shielding state or the transmission state. However, it may be a finely divided area, a panel unit, or an area unit. However, in the embodiment of the present disclosure, the description will be made with the panel 21 as a control unit unless otherwise noted.

  In FIG. 2, when the panel 21 is in the light blocking state, even if a person looks at the panel 21 with the naked eye, it can not recognize (see) an object present on the opposite side of the panel 21. It shall be. Further, when the panel 21 is in the transmission state, when a person looks at the panel 21 with the naked eye, an object present on the opposite side of the panel 21 can be recognized (viewed). In FIG. 2, the panel 21 in the transmission state is described as “panel 21”, and the panel 21 in the light shielding state is described as “panel 21 ′”.

  More specifically, for example, in the case where the light shielding wall 11 is placed on the near side and the conference room exists on the far side of the light shielding wall 11, the panel 21 is controlled to be in the light shielding state. As shown in the area W1 surrounded by the dotted line, the inside of the conference room can not be seen (not visible). In addition, as shown in the area other than the area W1, when the panel 21 is controlled to be in the transmission state, the inside of the conference room can be viewed (visible).

  The cameras 12-1 and 12-2 capture the first space and the second space described above, respectively, and supply the captured image to the control unit 13. In the following, when it is not necessary to distinguish between the cameras 12-1 and 12-2, in particular, the cameras 12-1 and 12-2 are simply referred to as the camera 12 and the other configurations are also referred to as the same. More specifically, the cameras 12-1 and 12-2 include optical blocks 12a-1 and 12a-2, image sensors 12b-1 and 12b-2, and signal processing units 12c-1 and 12c-2, respectively. There is. The optical block 12a is composed of at least one lens, condenses incident light, and causes the image sensor 12b to focus. The image sensor 12b converts focused light incident through the optical block into a signal according to the light amount and outputs the signal to the signal processing unit 12c in pixel units arranged in an array. The signal processing unit 12 c applies predetermined signal processing to the signal supplied from each pixel to generate an image composed of pixel signals, and outputs the generated image to the control unit 13. Here, each of the cameras 12-1 and 12-2 captures an image, and an image including data of distances from the cameras 12-1 and 12-2 in a space in the image of the subject captured for each pixel Capture the image. That is, the cameras 12-1 and 12-2 have a camera function called a so-called depth camera. Therefore, the images captured by the cameras 12-1 and 12-2 include information of the distance from the cameras 12-1 and 12-2 to the subject in pixel units, in addition to the normal image. Note that, hereinafter, an image including information on the distance in units of pixels is referred to as a distance image. Accordingly, the cameras 12-1 and 12-2 capture a normal image, generate a distance image, and supply the distance image to the control unit 13.

  The control unit 13 includes control circuits such as one or a plurality of CPUs (Central Processing Units), and the first space and the second space supplied from the cameras 12-1 and 12-2, respectively. Get an image of The control unit 13 recognizes the position of the object B1 in the first space based on the image of the first space and the information on the installation position and direction of the camera 12-1. Further, the control unit 13 determines the eye positions E1 and E2 of the eyes H1 and H2 of the persons H1 and H2 who do not want to show the object B1, based on the image of the second space and the information on the installation position and direction of the camera 12-2. Identify. Furthermore, the control unit 13 can be said to be the path of the line of sight when viewing the object B1 from the eye positions E1 and E2 of the persons H1 and H2 who do not want to show the object B1, and the eyes of the persons H1 and H2 who do not want to show the object B1. Optical paths L1 and L2 of the object B1 are obtained from the positions E1 and E2 of

  Furthermore, among the panels 21 on the light shielding wall 11, the control unit 13 controls the panel 21 including the intersection with the light paths L1 and L2 to the light shielding state and controls the other panels 21 to the transmission state. By controlling in this manner, for the persons H1 and H2 existing in the second space, the second space is made bright and open while maintaining a state in which B1 existing in the first space is not shown. It can be maintained as a space with That is, in the transmissive state, for example, as shown in the left part of FIG. 3, the room on the other side can be seen through the light shielding wall 11. On the other hand, in the light blocking state, as shown by the area W1 in the left part of FIG.

  In FIG. 1, the light path represents the line of sight when the eyes E1 and E2 of the persons H1 and H2 are the viewpoints, but the light path is transmitted or shielded against the light shielding wall 11 It only needs to indicate the path of light. Therefore, the light path does not necessarily indicate the line of sight. For example, a light path indicating the path of sunlight using the sun as a light source is also referred to as the light path. Therefore, in the following description, all paths of light transmitted through the light shielding wall 11 when the panels 21 of the light shielding wall 11 are controlled to be in the transmission state are referred to as optical paths.

  Further, as long as the position of the object B1 in the space can be recognized in advance, the camera 12-1 may be configured by only the camera 12-2 without being particularly required. Also, in the case of a sunlight using the sun as a light source, it can be regarded as substantially parallel light on the earth, and if the azimuth and the direction of the light shielding wall 11 can be recognized, the light path can be determined. It may be configured to have only two.

  Furthermore, in the above, the example has been described in which the panel 21 on the optical path where light which is not desired to be seen can be seen through the light blocking wall 11 for a predetermined user. Conversely, when there is an object that can be shown to a predetermined user through the light shielding wall 11 but that the user other than the predetermined user does not want to show, only the panel 21 on the optical path from the predetermined user to the object is displayed. Alternatively, the panels 21 may be in the light blocking state.

<< 2. First Embodiment >>
<Example of a light shielding device in which the outside of the light shielding wall can be visually recognized only by the user who approaches the light shielding wall>
The light shielding wall 11 described above can be used like a window glass when the panel 21 is in the transmission state, and can be functioned as a blind by being in the light shielding state. Therefore, in the first embodiment of the light shielding device to which the technology of the present disclosure is applied, an example in which the light shielding wall 11 described above is used as a window will be described.

  FIG. 4 uses the light shielding wall 11 as a window glass, and the predetermined light shielding wall 11 corresponds to the positional relationship between the light shielding wall 11 as a window and the specific part of the user near the light shielding wall 11. The example of a structure of the light shielding apparatus which makes the panel 21 of a range a transmission state, and controls the panel 21 of the other range into a light-shielding state is shown.

  The light shielding device shown in FIG. 4 can be used as a window by setting each panel 21 of the light shielding wall 11 in the transmission state, and the blindness can be obtained by changing the transmittance even in the light shielding state or the transmission state. It can also function as

  More specifically, the camera 12 in the light shielding device in FIG. 4 captures an interior of the room where the user H11 is present, and supplies the captured image to the control unit 13. The control unit 13 estimates the position of an eye as a specific part of the user H11 based on the captured image.

  When the position of the eye which is a specific part exists in the vicinity of the light shielding wall 11 as shown in the right part of FIG. When approaching the wall 11), the panel 21 in the area E11 of the light shielding wall 11 corresponding to the position of the eye, which is a specific part, is controlled to be in the transmission state.

  With this process, for example, as shown in the left part of FIG. 4, when using the blind in a light-shielded state, the blind slat (spring's splash) with a finger or the like is used to look outside. There is no need to bend it to create a space and to look out from the space.

<Configuration Example for Realizing the Light Shielding Device of FIG. 4>
Next, with reference to the block diagram of FIG. 5, the detailed configuration for realizing the light shielding device of FIG. 4 will be described. The light blocking wall 11 forming the window and the camera 12 have the same functions as those described with reference to FIGS. 1 to 3, and thus the description thereof is appropriately omitted.

  The control unit 13 includes an image acquisition unit 51, an acquired image determination unit 52, a light shielding transmission position calculation unit 53, a light shielding transmission storage unit 54, and a light shielding transmission control unit 55.

  The image acquisition unit 51 acquires a depth image captured by the camera 12 in the room where the user of the room in which the light shielding wall 11 is provided as a window is present, and supplies the depth image to the acquired image determination unit 52.

  The acquired image determination unit 52 analyzes the depth image supplied from the image acquisition unit 51, detects the presence or absence of the user in the depth image, and estimates the position of the user's eyes when the user exists, and further, If the estimated eye position is closer to the light shielding wall 11 than the predetermined distance (when the light shielding wall 11 is in the vicinity of the light shielding wall 11), information on the estimated eye position is supplied to the light shielding transmission position calculation unit 53 .

  The light shielding transmission position calculation unit 53 specifies the position of the panel 21 in the corresponding light shielding wall 11 based on the information on the eye position supplied from the acquired image determination unit 52, and sets the specified panel 21 in the transmission state. The light shielding transmission information is generated so as to control the other panels 21 in the light shielding state and is stored in the light shielding transmission storage unit 54 while controlling.

  The light shielding transmission information is information in which each panel 21 is set and registered in either the light shielding state or the transmission state, and the setting of the transmittance in the transmission state is registered. Therefore, the light shielding transmission position calculation unit 53 sets information on the light shielding transmission information as to whether each panel 21 is set to the light shielding state or the transmission state and the transmittance of the panel 21 set to the transmission state. Ru. In addition, although the transmittance | permeability in the case of being controlled by a permeation | transmission state shall be demonstrated as what is 1 here, the transmittance | permeability of other than that may be set. In addition, each panel 21 may be divided into smaller areas to control either the light shielding state or the transmission state, and in this case, the light shielding transmission information may be obtained by dividing each area in the light shielding state or the transmission state. It becomes information indicating which one is set. In addition, the information registered in the light blocking transmission information may be information indicating the transmittance or the light blocking ratio corresponding to the information indicating whether the light blocking state or the light transmitting state is set, for example, the transmittance It may be defined as = 1-blocking ratio.

  The light shielding transmission control unit 55 registers information on the light transmission state or light shielding state of each panel 21 in the light shielding wall 11 stored in the light shielding transmission storage unit 54, and information on each transmittance of the panel 21 to be transmitted. The light shielding state of each panel 21 of the light shielding wall 11 and the transmission state in consideration of the transmittance are controlled according to the light shielding transmission information.

<Partial transmission processing by the light shielding device in FIG. 5>
Next, partial transmission processing in the control unit 13 of the light shielding device in FIG. 5 will be described with reference to the flowchart in FIG.

  In step S <b> 11, the camera 12 captures the indoor side of the window formed by the light shielding wall 11 as a depth image, and supplies the depth image to the image acquisition unit 51.

  In step S12, the image acquisition unit 51 supplies the depth image supplied from the camera 12 to the acquired image determination unit 52.

  In step S13, the acquired image determination unit 52 detects the user's eyes as a specific part of the user from the depth image, specifies the position in the space, and is closer to the light shielding wall 11 than a predetermined distance. It is determined whether or not the user's eyes are present in the vicinity (near vicinity) of the light shielding wall 11 depending on whether or not the light shielding wall 11 is present, and the determination result is supplied to the light shielding transmission position calculation unit 53.

  More specifically, the acquired image determination unit 52 performs detection processing of a face image on the depth image to detect a face image. In addition, the acquired image determination unit 52 performs eye organ extraction from the detected face image. Furthermore, the acquired image determination unit 52 calculates the position of the window formed of the light shielding wall 11 in the space on the indoor side, based on the information of the distance in the depth image, which is the extracted organ, and the user's eyes It is determined whether or not the user's eye is in the vicinity of the light shielding wall 11 based on whether or not the position is within the predetermined distance from the light shielding wall 11. If there is no face image in the image taken by the camera 12 and, for example, only the back of the head etc. can be taken, the acquired image determination unit 52 extracts the image of the back of the head instead of the face image and extracts the image of the back of the head The position of the eye may be estimated from the position. When a moving image or the like is captured, the acquired image determination unit 52 detects the face image from the image of the scene in which the face image is captured, continuously tracks the position of the detected eye, and the face image For example, even in a scene where only the back of the head is shown, the position of the eye may be estimated.

  In step S13, for example, when it is considered that the user's eyes are closer than the predetermined distance from the light shielding wall 11, the acquired image determining unit 52 determines the information on the position of the user's eyes along with the determination result as the light shielding transmission position calculation unit Then, the process proceeds to step S14.

  In step S14, the light shielding transmission position calculation unit 53 stores information on the position in the space of the eye of the user, which is a specific part of the user.

  In step S <b> 15, the light shielding transmission position calculation unit 53 sets any unprocessed region of the predetermined regions set in units of panels 21 in the light shielding wall 11 as the processing target region.

  In step S16, the light shielding transmission position calculation unit 53 determines whether the position of the panel 21 in the processing target area is near the position in the space of the eye of the user, which is a specific part of the user. If it is determined in step S16 that the position of the panel 21 in the processing target area is near the position in the space of the user's eye, which is a specific part of the user, the process proceeds to step S17.

  In step S17, the light shielding transmission position calculation unit 53 stores the light shielding transmission information in the light shielding transmission storage unit 54 as controlling the panel 21 in the processing target region into the transmission state. In accordance with this process, the light shielding transmission control unit 55 controls the panel 21 in the processing target area to the light transmitting state based on the light shielding transmission information stored in the light shielding transmission storage unit 54.

  On the other hand, if it is determined in step S16 that the position of the panel 21 in the processing target area is not near the position in the space of the user's eye, which is a specific part of the user, the process proceeds to step S18.

  In step S <b> 18, the light shielding transmission position calculation unit 53 stores the light shielding transmission information in the light shielding transmission storage unit 54 as controlling the panel 21 in the processing target region to the light shielding state. In accordance with this process, the light shielding transmission control unit 55 controls the panel 21 in the processing target area to the light shielding state based on the light shielding transmission information stored in the light shielding transmission storage unit 54.

  In step S19, the light shielding transmission position calculation unit 53 determines whether or not there is an unprocessed area in the area of the panel 21 unit in the light shielding wall 11. If there is an unprocessed area, the process is Return to S15. That is, the processes of steps S15 to S19 are repeated until there is no unprocessed area. When it is determined in step S19 that there is no unprocessed area, the process proceeds to step S20. If it is determined in step S13 that the user's eyes are not closer than the light shielding wall 11 by a predetermined distance, the processing in steps S14 to S19 is skipped.

  In step S20, the acquired image determination unit 52 determines whether or not the end of the process is instructed. If the end is not instructed, the process returns to step S11, and the subsequent process is repeated. Then, in step S20, when it is considered that the end is instructed, the process is ended.

  That is, as shown in the right part of FIG. 4, when the user causes the eye to approach the window formed by the light shielding wall 11, the panel 21 at the position corresponding to the approached eye is controlled to the transmission state. The other panels 21 are in the light blocking state, and in the other states, the entire panel 21 is controlled in the light blocking state.

  For this reason, all panels 21 are controlled to be in the light blocking state until the user brings the eyes close, so the appearance on the indoor side where the user of the window consisting of the light blocking wall 11 is present will be invisible from the outside. It is possible to maintain privacy in the room where In addition, when the user in the room wants to look outside the window formed of the light shielding wall 11 while maintaining the state in which the privacy is held in this way, only the panel 21 near the eyes is transmitted by merely approaching the eyes. Because it is controlled to, it is possible to look at the situation outside the room.

  Although the example of specifying the position of the user's eye using the depth image captured by the camera 12 has been described above, the position of the eye may be specified using a two-dimensional image. Good. Also, even if the face or eyes are not shown in the image taken by the camera 12, tracking the movement of the eyes from the image where the eyes are taken by using an image taken continuously by a moving image or the like Then, the position of the eye in the image in which the face or the eye is not seen may be estimated.

  Furthermore, the position of the eye approaching the window formed by the light shielding wall 11 may be detected from other than the depth image captured by the camera 12 or a normal two-dimensional image. For example, the position of the eye is shielded For example, an infrared sensor or the like may be used as to whether or not it is specified at a stage before approaching the wall 11 and whether it is within the predetermined distance.

  In the above, an example in which the user exists indoors has been described. However, when the user exists outdoors and looks into the light shielding wall 11 from the outside, the panel 21 of the region corresponding to the eye position is transmitted through The control may be performed to control the other panels 21 in the light shielding state so that the room can be seen from the outside. However, in this case, the camera 12 needs to be configured to pick up an image outside the room.

<< 3. Second embodiment >>
In the above, the light shielding wall 11 is applied as a window, and when the user's eyes are in the vicinity of the light shielding wall 11 and approach within a predetermined distance, based on the state around the window formed of the light shielding wall 11 The example which controls the panel 21 of the area | region corresponding to the position of (4) to a permeation | transmission state, and controls the panel 21 of the area | region of other than that to a light-shielding state was demonstrated. However, in this example, since it is assumed that the light shielding wall 11 is controlled to be in the light shielding state as a whole, the state outside the window formed of the light shielding wall 11 can not be seen.

  For this reason, the window formed of the light shielding wall 11 is used, for example, as a boundary between a breeding room of an animal to be observed in a zoo and a space for observation of visitors of the zoo (hereinafter also referred to as observation space). When considering this, the window consisting of the light shielding wall 11 is always in the light shielding state, and it is necessary for the visitor to approach the window consisting of the light shielding wall 11 and bring the eyes closer in order to see the animals in the breeding room . This makes it difficult for many visitors to observe the animals at the same time.

  Therefore, when the boundary between the breeding room and the observation space is configured using a window made of the light shielding wall 11, a camera 12-1 for imaging each of the breeding room and the observation space as shown by the light shielding device in FIG. , 12-2. Then, as shown by the animal A1 in the breeding room on the left side of FIG. 7, when the animal A1 can not look at the light shielding wall 11 with the back facing the light shielding wall 11, the control unit 13 Control the whole of 11 in the transparent state. On the other hand, as shown by the animal A2 in the breeding room on the right side of FIG. 7, when the animal A2 faces the light shielding wall 11, the control unit 13 causes the light shielding wall 11 to be partially transparent as described above. You may

  With such a configuration, even if, for example, an animal that is scared of humans is being bred in a breeding room in a zoo, such as when the animal looks at the window formed of the light blocking wall 11, the light is blocked. Being controlled to the state, it is possible for the bred animal to be in a state where it is not necessary to be aware of the visitor's eyes. In addition, if the visitor approaches the light shielding wall 11 and brings his eyes close, only the panel 21 near the eyes is controlled to be in the transmission state, and it is possible to observe animals without being surprised. Moreover, when the animal does not look at the window which consists of the light-shielding wall 11, many visitors can observe the animal in a breeding room simultaneously by controlling the whole panel 21 of the light-shielding wall 11 in the permeation | transmission state can do. In any case, since the panel 21 of the light shielding wall 11 can be controlled to the light shielding state or the transmission state based on the state of the animal and the light shielding wall 11, according to the state without alarming the animal. Many visitors can observe animals at the same time.

<Configuration Example to Realize the Light Shielding Device of FIG. 7>
Next, with reference to the block diagram of FIG. 8, a detailed configuration for realizing the light shielding device of FIG. 7 will be described. The light blocking wall 11 forming the window and the camera 12 have the same functions as those described with reference to FIGS. 1 to 3, and thus the description thereof is appropriately omitted. Further, in the configuration of FIG. 8, components having the same functions as those of the configuration of FIG. 5 are given the same reference numerals and the same names, and the description thereof will be appropriately omitted.

  That is, in the light shielding apparatus shown in FIG. 8, the camera 12 is different from the light shielding apparatus shown in FIG. 5 in that the cameras 12-1 and 12-2 are provided with the image acquisition units 51-1 and 51-2, respectively. Furthermore, instead of the acquired image determination unit 52 and the light shielding transmission position calculation unit 53, an acquired image determination unit 71 and a light shielding transmission position calculation unit 72 are provided.

  Although the cameras 12-1 and 12-2 and the image acquisition units 51-1 and 51-2 are the same as the camera 12 and the image acquisition unit 51, the camera 12-1 images the observation space and the camera 12-2 images a breeding room.

  The acquired image determination unit 71 basically performs the same process as the acquired image determination unit 52, but determines the state of the animal in the breeding room and causes the determination result to be a light shielding transmission position calculation unit 72. That is, based on the image in the breeding room supplied by the image acquiring unit 51-2 and captured by the camera 12-2, the acquired image determination unit 71 sets the light shielding wall 11 within the field of view of the animal in the breeding room. It is determined whether or not the condition is present (the condition that the visitor can see through the window formed by the light shielding wall 11), and the determination result is supplied to the light shielding transmission position calculation unit 72.

  The light shielding transmission position calculation unit 72 basically performs the same processing as the light shielding transmission position calculation unit 53, but a state in which the light shielding wall 11 is included in the visual field of the animal in the breeding room (from the light shielding wall 11 Processing is performed according to the determination result of whether or not the guest can see through the window

  That is, when the light shielding wall 11 is included in the field of view of the animal in the breeding room based on the image in the breeding room, which is captured by the camera 12-2 (the light blocking wall When the determination result that the guest is in a state where the guest sees through the window 11 is supplied), and the image captured by the camera 12-1 is supplied from the image acquisition unit 51-1. The acquired image determination unit 71 executes the same process as the partial transmission process described above.

  Further, based on the image in the breeding room taken by the camera 12-2, the light blocking transmission position calculation unit 72 does not include the visitor through the window made of the light blocking wall 11 in the field of view of the animal in the breeding room When the determination result that the state is the state is supplied, all the panels 21 of the light shielding wall 11 are controlled to be in the transmission state.

<Partial transmission processing by the light shielding device in FIG. 8>
Next, with reference to the flowchart of FIG. 9, the observation processing in the control unit 13 of the light shielding device of FIG. 8 will be described. Here, the case of observing an animal as an example will be described, but the observation target may be a living thing, an inanimate object equipped with a camera, or the like.

  In step S31, the camera 12-2 captures the breeding room side of the window formed by the light shielding wall 11 as a depth image, and supplies the depth image to the image acquisition unit 51-2.

  In step S32, the image acquisition unit 51-2 supplies the depth image supplied from the camera 12-2 to the acquired image determination unit 71.

  In step S33, the acquired image determination unit 71 detects the face as a specific part of the animal from the depth image in the breeding room, identifies the position in the breeding room, and determines whether the light shielding wall 11 exists in the animal's field of view. The determination result is supplied to the light shielding transmission position calculation unit 72.

  More specifically, the acquired image determination unit 71 performs detection processing of a face image of an animal on a depth image to detect a face image of the animal. Further, the acquired image determination unit 71 performs eye organ extraction from the detected face image. Furthermore, the acquired image determination unit 71 determines whether or not the window formed by the light shielding wall 11 is within the field of view of the animal in the breeding room based on the information of the distance in the depth image which is the extracted organ eye. Do.

  In step S33, for example, when there is a window made of the light shielding wall 11 in the visual field of the animal in the breeding room and the visitor can visually recognize, the process proceeds to step S34.

  In step S34, the light shielding transmission position calculation unit 72 described above according to the determination result of the acquired image determination unit 71 based on the image from the image acquisition unit 51-1 that acquires the image captured by the camera 12-1. Perform partial transparency processing. The partial transmission process in step S34 is a series of processes consisting of steps S11 to S19 in FIG. 6 and is the same as the above description, and thus the description thereof will be omitted.

  That is, in the present case, there is a window consisting of the light shielding wall 11 within the field of view of the animal in the breeding room, and the animal is in a state where the visitor can see through the window. There is a fear that the behavior can not be taken and the animal's original behavior can not be observed. Therefore, in this case, the whole of the light shielding wall 11 is in the light shielding state, and the part corresponding to the eyes is made in the transmission state by bringing the visitor closer to the light shielding wall 11 by the partial transmission processing. Then, by making it possible to observe the animals in the breeding room so that they can be observed, it is possible to appropriately observe the original behavior of the animals without being surprised by the animals in the breeding room.

  On the other hand, in step S33, for example, when there is no window consisting of the light shielding wall 11 in the visual field of the animal in the breeding room, and the visitor can not be seen from the animal through the window, the process proceeds to step S35.

  In step S35, the light shielding transmission position calculation unit 72 controls all the panels 21 of the light shielding wall 11 to the transmission state based on the determination result.

  That is, in the present case, there is no window consisting of the light shielding wall 11 in the field of view of the animal in the breeding room, and the visitor is not visible through the window. It is a state where you can act without worrying. Therefore, in this case, all the panels 21 of the light shielding wall 11 are controlled to be in the transmission state, and the visitor can observe the animals in the breeding room even if they are separated from the window formed of the light shielding wall 11 Multiple guests can observe the animals at the same time. Note that, in step S35, the control unit 13 does not have to make all the regions transparent, and the control unit 13 sets the processing to make the regions larger (wider) than the regions controlled to be transparent by at least partial transmission processing. You may go.

  In step S36, the acquired image determination unit 71 determines whether or not the end of the process is instructed. If the end is not instructed, the process returns to step S31, and the subsequent processes are repeated. Then, in step S36, when it is considered that the end is instructed, the process is ended.

  That is, as shown by the animal A1 on the left side of FIG. 7, the animal A1 does not look toward the window formed of the light shielding wall 11 by the above-described processing, and the visitor is made through the window formed of the light shielding wall 11 When the figure to be observed is a state which can not be seen from the animal A1, all panels 21 of the light shielding wall 11 are in a transmission state, and the visitor threatens the animal A1 in the breeding room even from a position away from the light shielding wall 11 It is possible to observe the original activity of the animal.

  In addition, as shown by the animal A2 in the right part of FIG. 7, the animal A2 is looking at the window formed of the light shielding wall 11, and the animal A2 can see the visitor through the window formed of the light shielding wall 11. When it is, by performing the above-mentioned partial transmission processing, only the visitor who brought the eye close to the light shielding wall 11 controls only the part of the panel 21 corresponding to the eye that has come close to the transmission state. It will be observed the animals. In this case, only the part of the visitor's eyes is controlled to be in the transparent state, and the animal A2 can not see the appearance of the visitor, so appropriately observe the original behavior of the animal without being surprised by the animal It becomes possible.

  In the above, depending on whether or not the animal looks at the window made of the light shielding wall 11, it has been described whether the light shielding wall 11 is partially transparent or whether all the panels 21 are controlled to be transparent. It is fine as long as the animal in the breeding room can not see the visitor through the window made of the light shielding wall 11, so it is not always necessary to determine whether the window made of the light shielding wall 11 is present in the animal's field of view. If the distance is greater than the predetermined distance, the visitor can not see through the window made of the light shielding wall 11 even if it is in the field of view. The panel 21 may be controlled to be in the transmission state.

  In the case where a plurality of animals are present in the breeding room, all panels 21 are controlled to be in the transmission state only when there is no window consisting of the light shielding wall 11 in any field of view of the plurality of animals. In other cases, partial transmission processing may be performed.

<< 4. Third Embodiment >>
In the above, the light blocking wall 11 is applied to the window at the boundary between the observation space and the breeding room, and when there is no window consisting of the light blocking wall 11 in the field of view of the animals in the breeding room For the cases other than the above, an example of partially transmitting has been described. However, the light shielding wall 11 may be used as a floor, not as a window, and the transmission state or the light shielding state may be controlled according to the state of the user on the floor.

  FIG. 10 shows an embodiment of a light shielding device which uses the light shielding wall 11 as a floor and controls the panel 21 to be in the transmission state or the light shielding state according to the state of the user on the floor.

  That is, as shown in the left part of FIG. 10, in the light shielding device of FIG. 10, the floor 91 of the observation room 81a of the tower 81 for sightseeing is constituted by the light shielding wall 11, and the upper part of the right part of FIG. As shown in the figure, each panel 21 is controlled to be in the light blocking state or in the light transmitting state in accordance with the state of the user on the light blocking wall 11 as a floor.

  More specifically, as shown in the lower left portion of the right portion of FIG. 10, the camera 12 captures an image on the floor 91 formed of the light shielding wall 11 in the observation room 81a, and the control unit based on the captured image 13 controls the panel 21 of the area 11a in which the visitor (user) H31 has stepped into to a light shielding state, and controls the other panels 21 to a transmission state.

  Further, the conditions of the light blocking state and the light transmitting state may be reversed, for example, as shown in the lower right portion of the right portion of FIG. 10, the camera 12 is on the floor 91 consisting of the light blocking wall 11 in the observation room 81a. Is captured, and based on the captured image, the control unit 13 controls the panel 21 of the area 11b in which the visitor user (user) H31 has stepped into to the transmission state, and controls the other panels 21 to the light shielding state Do.

  With such a configuration, an effect is produced that only the feet of the visitor H 31 in the observation room 81 a as the user move on the floor 91 so that only their feet are controlled to be in the light blocking state or are controlled to be in the transmitting state. Makes it possible to enjoy various views.

<Example of configuration for realizing the light shielding device of FIG. 10>
Next, with reference to the block diagram of FIG. 11, the detailed configuration for realizing the light shielding device of FIG. 10 will be described. The light shielding wall 11 constituting the floor 91 and the camera 12 have the same functions as those described with reference to FIGS. 1 to 3, and thus the description thereof is appropriately omitted. Further, in the configuration of FIG. 11, the same reference numerals and the same names are given to configurations having the same functions as the configuration of FIG. 5, and the description thereof will be appropriately omitted.

  That is, the light shielding device of FIG. 11 differs from the light shielding device of FIG. 5 in that the acquired image judgment unit 111 and the light shielding transmission position calculation unit 112 replace the acquired image judgment unit 52 and the light shielding transmission position calculation unit 53. It is a point provided.

  Further, based on the depth image supplied from the image acquisition unit 51, the acquired image determination unit 111 specifies, within the image, the position of the foot that the visitor who is the user in the observation room 81a has stepped onto the floor 91, Furthermore, based on the information of the distance of the depth image, the position of the space in the observation room 81 a of the foot that has been stepped in is specified, and is supplied to the light shielding transmission position calculation unit 112.

  The light shielding transmission position calculation unit 112 specifies the panel 21 on the light shielding wall 11 constituting the floor 91 of the observation room 81 a corresponding to the position of the space in the observation room 81 a of the foot and shields the specified panel 21 Alternatively, it is controlled to be in the transmission state, and transmission / shielding information is generated so as to control the other panels 21 to be in the transmission state or in the light shielding state, and stored in the transmission / light shielding storage unit 54.

  With such a configuration, only the panel 21 at the foot of the visitor on the floor 91 of the observation room 81a is controlled to be in the light blocking or transmitting state, and the other panels 21 are controlled to be in the transmitting or blocking state. . By such an effect, when the visitor walks on the floor 91 of the observation room 81a, only the panel 21 of the floor 91, which he has stepped in, enters the light shielding state or the transmission state as the foot moves. It becomes possible to enjoy the effect of being controlled.

<Partial floor transmission processing by the light shielding device of FIG. 11>
Next, a partial floor transmission process in the control unit 13 of the light shielding device of FIG. 11 will be described with reference to the flowchart of FIG.

  In step S51, the camera 12 captures an observation room 81a on the floor 91 formed of the light shielding wall 11 as a depth image, and supplies the same to the image acquisition unit 51.

  In step S52, the image acquisition unit 51 supplies the depth image supplied from the camera 12 to the acquired image determination unit 111.

  In step S53, the acquired image determination unit 11 detects the foot on which the visitor has stepped on the floor 91 from the depth image, and whether or not the visitor has stepped on the floor 91 made of the light shielding wall 11 of the observation room 81a. The determination result is supplied to the light shielding transmission position calculation unit 112.

  More specifically, the acquired image determination unit 111 performs detection processing of the foot image on the depth image to detect the foot. Also, based on the information on the distance within the depth image from the detected image of the foot, the acquired image determination unit 111 determines whether the foot is present on the floor 91 formed of the light shielding wall 11 and the visitor is stepping on the foot It is determined whether or not.

  In step S53, for example, if the foot of the visitor is present on the floor 91 constituted by the light shielding wall 11 and the visitor is considered to be stepping on the floor 91, the process proceeds to step S54. Then, along with the determination result, information on the position of the foot of the visitor is supplied to the light shielding transmission position calculation unit 112.

  In step S54, the light shielding transmission position calculation unit 112 stores information on the position of the floor 91 in the observation room 81a of the foot of the visitor.

  In step S55, the light shielding transmission position calculation unit 112 sets any unprocessed region among the predetermined regions set in units of panels 21 in the light shielding wall 11 constituting the floor 91 as the processing target region.

  In step S56, the light shielding transmission position calculation unit 112 determines whether or not the position of the panel 21 in the processing target area is a position near the area on the floor 91 in the observation room 81a of the foot of the visitor. If it is determined in step S56 that the position of the panel 21 in the processing target area is a position near the area on the floor 91 in the observation room 81a of the foot of the visitor, the process proceeds to step S57.

  In step S57, the light shielding transmission position calculation unit 112 stores the light shielding transmission information in the light shielding transmission storage unit 54 as controlling the panel 21 in the processing target region to the light shielding state. In accordance with this process, the light shielding transmission control unit 55 controls the panel 21 in the processing target area to the light shielding state based on the light shielding transmission information stored in the light shielding transmission storage unit 54.

  On the other hand, if it is determined in step S56 that the position of the panel 21 in the processing target area is not a position near the area on the floor 91 in the observation room 81a of the foot of the visitor, the process proceeds to step S58 .

  In step S58, the light shielding transmission position calculation unit 112 stores the light shielding transmission information in the light shielding transmission storage unit 54 as controlling the panel 21 in the processing target region into the transmission state. In accordance with this process, the light shielding transmission control unit 55 controls the panel 21 in the processing target area to the light transmitting state based on the light shielding transmission information stored in the light shielding transmission storage unit 54.

  In step S59, the light shielding transmission position calculation unit 112 determines whether or not there is an unprocessed area in the area of the panel 21 unit in the light shielding wall 11. If there is an unprocessed area, the process is Return to S55. That is, the processes of steps S55 to S59 are repeated until there is no unprocessed area. When it is determined in step S59 that there is no unprocessed area, the process proceeds to step S60. If it is determined that the foot of the visitor does not step on the floor 91 formed of the light shielding wall 11 in step S53, the processes of steps S54 to S59 are skipped.

  In step S60, the acquired image determination unit 111 determines whether or not termination of the process is instructed. If termination of the process is not instructed, the process returns to step S51, and the subsequent processes are repeated. Then, in step S60, when it is considered that the end is instructed, the process is ended.

  That is, as shown in the right part of FIG. 10, when the visitor steps on the floor 91 made of the light shielding wall 11 by the above process, the panel 21 at the position on which the foot is placed is controlled to the light shielding state. The other panels 21 are in the transmission state, and in the other states, the entire panel 21 is controlled in the transmission state.

  For this reason, all panels 21 are controlled to be in the transmission state until the visitor steps on the floor 91. Therefore, when the foot is stepped on the floor 91 made of the light shielding wall 11, the panel 21 of the portion that becomes one's foot Since only the light shielding state is in the light shielding state, it is possible to realize an effect that a footstep can be made as if stepping on the foot. Further, it is possible to realize such an effect that the panel 21 to be a light-shielding state as a footstep appears sequentially in the lower part of the foot which is stepped as the foot which has been walked walking on the floor 91 moves.

  In the above, the example in which the panel 21 at the position where the foot is depressed is controlled to the light shielding state and the other panels 21 are controlled to the transmission state, the control of the light shielding state and the transmission state is reversed It may be By doing this, the floor 91 is controlled to be entirely shielded from light until the visitor enters the foot, and the visitor enters the foot at the moment the panel of the floor 91 at the foot By controlling 21 in the transmission state, it is possible to produce an effect as if the floor 91 at the position where the user has stepped in has fallen off.

  In the above, an example of specifying the position of the foot of the visitor using the depth image captured by the camera 12 has been described, but sensor data obtained by a two-dimensional image or another sensor is used. The position of the foot may be specified.

  Furthermore, the position of the foot on the floor 91 formed of the light shielding wall 11 may be detected from other than from a depth image captured by the camera 12 or a normal two-dimensional image, for example, an infrared sensor or a touch sensor The position of the foot may be detected using

  Also, in the above, an example in which the floor 91 of the foot is controlled to be in the transmission state or the light blocking state when the visitor steps on the floor 91 of the observation room 81a has been described. Control the panel 21 constituting the ceiling right above the ceiling when the visitor steps into the observation room 81a or the like to the transmission state or the light shielding state, and control the other panels 21 to the light shielding state or the transmission state You may do so.

<< 5. Fourth Embodiment >>
In the above, the light shielding wall 11 is applied as the floor 91 of the observation room 81 a of the tower 81 for sightseeing, and when the visitor steps into the floor 91 consisting of the light shielding wall 11, the foot of the visitor on the floor 91 The example which controls the panel 21 of a corresponding area | region to a light-shielding state or a permeation | transmission state, and controls the panel 21 of the other area | region to a permeation | transmission state or a light-shielding state has been demonstrated. However, the light shielding wall 11 is used as a window, and according to the presence or absence of an approach of a suspicious person as a peripheral state of the window, it is controlled to be in a transparent state or a light shielding state. You may do it.

  FIG. 13 uses the light shielding wall 11 as a window, detects the presence or absence of an approach of a suspicious person as a peripheral state of the window, and controls the light shielding state of the panel 21 of the light shielding wall 11 constituting the window or the light shielding state. Fig. 9 shows an embodiment of a light shielding device adapted to control locking and unlocking of a window key.

  That is, in the light shielding device shown in FIG. 13, when an outdoor image taken by the camera 12 and outside the window formed by the light shielding wall 11 is supplied to the control unit 13, the control unit 13 sends the suspicious person H51 over the image. When the suspicious person H51 is detected, the panel 21 of the area corresponding to the visual field range of the suspicious person H51 is controlled to be in the light shielding state among the light shielding walls 11 constituting the window, and the window key and The smart lock 121 is controlled to be in the locked state. In addition, when a suspicious person is not detected, the control unit 13 controls all panels 21 of the light shielding wall 11 constituting the window to the transparent state, and controls the smart lock 121 as a window key to release the lock. Control.

  By this configuration, it is possible to suppress the intrusion of the suspicious person, and even when the user who is a resident is present indoors inside the window formed of the light shielding wall 11, it may be possible to match the suspicious person. By restraining, it becomes possible to deter the crime that a resident can be harmed by a suspicious person. In addition, since the smart lock 121 is unlocked when there is no suspicious person, the resident user can easily open and close the window without being aware of locking and unlocking, while the intrusion of the suspicious person is It becomes possible to prevent.

<Example of configuration for realizing the light shielding device of FIG. 13>
Next, with reference to the block diagram of FIG. 14, the detailed configuration for realizing the light shielding device of FIG. 13 will be described. The light blocking wall 11 forming the window and the camera 12 have the same functions as those described with reference to FIGS. 1 to 3, and thus the description thereof is appropriately omitted. Further, in the configuration of FIG. 14, components having the same functions as those of the configuration of FIG. 5 are given the same reference numerals and the same names, and the description thereof will be appropriately omitted.

  That is, the light shielding device of FIG. 14 differs from the light shielding device of FIG. 5 in that the acquired image judgment unit 52 and the light shielding transmission position calculation unit 53 are replaced by an operation judgment unit 151 and a light shielding transmission position calculation unit 152. And a smart lock control unit 153 is newly provided to control the unlocking and locking of the smart lock 121.

  In addition, the operation determination unit 151 determines the presence or absence of a suspicious person based on the depth image supplied from the image acquisition unit 51, and when there is a suspicious person, the light shielding wall 11 serving as the visual field range of the suspicious person The information on the area of the window is provided to the light shielding transmission position calculation unit 152, and the presence or absence of a suspicious person is supplied to the smart lock control unit 153.

  The light shielding transmission position calculation unit 152 specifies the position of the corresponding panel 21 when acquiring the information of the window area consisting of the light shielding wall 11 serving as the visual field range of the suspicious person, together with the determination result indicating that the suspicious person is detected. When the suspicious person is not detected, all the panels 21 of the light shielding wall 11 are brought into the light transmission state.

  The smart lock control unit 153 controls to lock the smart lock 121 which is the window key when a suspicious person is detected, and controls to unlock the smart lock 121 when a suspicious person is not detected.

  With such a configuration, in the light shielding wall 11 as a window, when the approach of a suspicious person is detected, the panel 21 of the area serving as the visual field range of the suspicious person is controlled to the light shielding state, and the other panels 21 are in the transmission state And the smart lock 121 is locked. When the approach of a suspicious person is not detected, all the panels 21 are controlled to be in the transparent state, and the smart lock 121 is unlocked.

<Anti-crime process by the light shielding device of FIG. 14>
Next, the crime prevention process in the control unit 13 of the light shielding device in FIG. 14 will be described with reference to the flowchart in FIG.

  In step S <b> 71, the camera 12 captures an outside of the vicinity of the window formed by the light shielding wall 11 as a depth image and supplies the same to the image acquisition unit 51.

  In step S72, the image acquisition unit 51 supplies the depth image supplied from the camera 12 to the operation determination unit 151.

  In step S73, the operation determination unit 151 detects a suspicious person by analyzing the depth image, and determines the presence or absence of the suspicious person near the window formed by the light shielding wall 11.

  More specifically, the operation determination unit 151 previously registers the face image of the user who is the resident of the room inside the window formed by the light shielding wall 11 in the storage unit (not shown) in advance and detects the face image from the depth image Then, it compares with the registered resident's face image, and determines the presence or absence of a suspicious person based on whether or not they match. In addition, when a moving image is captured by the camera 12, the operation determination unit 151 detects a person from the moving image, and continuously analyzes the detected movement of the person to detect a suspicious person. May be That is, the operation determination unit 151 compares the operation of the person captured as a moving image with the operation registered in advance in the storage unit (not shown) as the suspicious operation, and the suspicious person is determined based on whether or not they match. It may be determined whether there is any.

  For example, when the face image is detected, the operation determination unit 151 compares the face image with the face image of the user who is a resident registered in advance and matches the face image when the face image is detected. The presence or absence of a suspicious person is determined by whether or not it is. The operation determination unit 151 determines that there is no suspicious person when no face image is detected.

  If it is determined in step S73 that a suspicious person is present, the process proceeds to step S74.

  In step S74, the operation determination unit 151 supplies the smart lock control unit 153 with a determination result indicating that there is a suspicious person. Based on the determination result, the smart lock control unit 153 controls the smart lock 121 in the locked state.

  In step S75, the operation determination unit 151 specifies the position with respect to the window formed by the light shielding wall 11 from the position in the depth image of the face image of the suspicious person in the detected image, and obtains the visual field range of the suspicious person It is stored in the transmission position calculation unit 152.

  In step S76, the light shielding transmission position calculation unit 152 sets any unprocessed region among the predetermined regions set in units of panels 21 in the light shielding wall 11 forming the window as the processing management region.

  In step S77, the light shielding transmission position calculation unit 152 determines whether the position of the panel 21 in the processing target area is a position near the area of the visual field range of the suspicious person. If it is determined in step S77 that the position of the panel 21 in the processing target area is a position near the area within the visual field range of the suspicious person, the process proceeds to step S78.

  In step S 78, the light shielding transmission position calculation unit 152 stores the light shielding transmission information in the light shielding transmission storage unit 54 as controlling the panel 21 in the processing target region to the light shielding state. In accordance with this process, the light shielding transmission control unit 55 controls the panel 21 in the processing target area to the light shielding state based on the light shielding transmission information stored in the light shielding transmission storage unit 54.

  On the other hand, if it is determined in step S77 that the position of the panel 21 in the processing target area is not a position near the area within the visual field range of the suspicious person, the process proceeds to step S79.

  In step S79, the light shielding transmission position calculation unit 152 stores the light shielding transmission information in the light shielding transmission storage unit 54 as controlling the panel 21 in the processing target region into the transmission state. In accordance with this process, the light shielding transmission control unit 55 controls the panel 21 in the processing target area to the light transmitting state based on the light shielding transmission information stored in the light shielding transmission storage unit 54.

  In step S80, the light shielding transmission position calculation unit 152 determines whether or not there is an unprocessed area in the area of the panel 21 unit in the light shielding wall 11. If there is an unprocessed area, the process is Return to S76. That is, the processes of steps S76 to S80 are repeated until there is no unprocessed area. When it is determined in step S80 that there is no unprocessed area, the process proceeds to step S81.

  In step S81, the acquired image determination unit 111 determines whether or not termination of the process is instructed. If termination of the process is not instructed, the process returns to step S71, and the subsequent processes are repeated. Then, in step S81, when it is considered that the end is instructed, the process is ended.

  If it is determined in step S73 that a suspicious person is not present near the window formed by the light shielding wall 11, the process proceeds to step S82.

  In step S <b> 82, the operation determination unit 151 supplies the smart lock control unit 153 with a determination result indicating that there is no suspicious person. Based on the determination result, the smart lock control unit 153 controls the smart lock 121 to be in a released state (locked state).

  In step S83, the operation determination unit 151 instructs the light shielding transmission position calculation unit 152 to control all the panels 21 in the light shielding wall 11 into the transmission state. Thereby, the light shielding transmission position calculation unit 152 generates the light shielding transmission information so as to control all the panels 21 in the light transmission state, and stores the light shielding transmission information in the light shielding transmission storage unit 54. By this processing, the light shielding transmission control unit 55 controls all the panels 21 in the transmission state.

  That is, as shown in FIG. 13, when the suspicious person is detected in the vicinity of the window formed by the light shielding wall 11 by the above processing, the panel 21 corresponding to the area on the light shielding wall 11 which becomes the visual field range of the suspicious person. Is controlled to the light shielding state, and the other panels 21 are in the transmission state, and the smart lock 121 is in the locked state. Further, when a suspicious person is not detected, the entire panel 21 is controlled to be in a transparent state, and the smart lock 121 is unlocked.

  For this reason, the user who is locked by the smart lock 121 only when a suspicious person approaches, and is in the unlocked state in other states, the user who becomes the resident of the indoor located inside the window formed of the light shielding wall 11 It is possible to open and close the window formed of the light shielding wall 11 without being conscious of locking and unlocking.

  In addition, even if a resident may be present indoors when a suspicious person approaches, it is possible to suppress a situation where a suspicious person is in a match, so for a user whose resident is a suspicious person It is possible to control crimes that cause harm.

<< 6. Fifth Embodiment >>
In the above, the light shielding wall 11 is used as a window, and according to the presence or absence of the approach of the suspicious person as the state around the window, the light transmitting state or the light shielding state is controlled, and correspondingly, the locking and unlocking of the window key An example has been described to control the However, the present invention is not limited to this, for example, by providing a road wall consisting of the light shielding wall 11 at the boundary between the road and the living area along the road, the passenger area of the passenger of the vehicle The visible range may be controlled to the light shielding state, and the other range may be controlled to the transmitting state.

  In FIG. 16, the road wall consisting of the light shielding wall 11 is provided at the boundary between the road and the living area along the road, and the living area can be seen from the passenger of the vehicle according to the position of the vehicle traveling on the road. The example of the light-shielding apparatus which controlled the panel 21 of the road wall of a range in the light-shielding state, and controlled the panel 21 of the other range in the permeation | transmission state is shown.

  That is, in the light shielding device of FIG. 16, a vehicle traveling on the road 171 is imaged by the camera 12 provided on the road 171 and supplied to the control unit 13, and the control unit 13 is identified from the image. From the position, the panel 21 of the light shielding wall 11 corresponding to the range where the occupant area of the vehicle can be seen from the position of the vehicle is controlled to the light shielding state, and the others are controlled to the transmission state.

  More specifically, for example, as shown in FIG. 17, a road wall consisting of the light shielding wall 11 is provided at the boundary between the road 171 and the living area 172, and the light shielding wall 11 is provided along the road 171, for example. The panels 21-1 to 21-8, which constitute the light shielding wall 11, are individually controlled to be in the light shielding state or the transmission state. Further, as shown by the cameras 12-1 and 12-2, it is provided in the central separation zone of the road 171, and images the traveling vehicle 181 and supplies it to the control unit 13.

  Here, for example, it is assumed that the vehicle 181 is traveling from the left side to the right side in the drawing. At this time, the camera 12-1 captures an image of the vehicle 181-1 on the right side of the vehicle 181 as a depth image, and supplies the depth image to the control unit 13. The control unit 13 obtains the positional relationship between the vehicle 181-1 and the living area 172 from the depth image, and is controlled to be in the transmission state among the panels 21 constituting the light shielding wall 11 from the passenger of the vehicle 181-1 The panel 21 in the range where the living area 172 can be seen through the panels 21 is controlled to be in the light shielding state, and the other panels 21 are controlled to be in the transmission state. In FIG. 17, only the panels 21-3 to 21-5 are controlled to be in the light shielding state, and the other panels 21 are controlled to be in the transmitting state.

  Furthermore, when the vehicle 181-1 moves to the position of the vehicle 181-2 on the right side in the drawing with the passage of time, the control unit 13 puts only the panels 21-1 to 21-4 of the light shielding wall 11 in the light shielding state. It controls and controls the panel 21 other than that to a permeation | transmission state.

  That is, on the road wall consisting of the light shielding wall 11, the vehicle 181 traveling on the road 171 approaches the living area 172, and only the panel 21 in the range where the living area 172 can be seen from the passenger of the vehicle 181 is blocked. The range panel 21 is brought into the transparent state.

  As a result, at the timing when the vehicle 181 travels on the road 171 and approaches the living area 172, only the panel 21 in the range visible to the passenger is controlled to be in the light shielding state. It is possible to protect. Moreover, since the panel 21 of the light shielding wall 11 constituting the road wall is maintained in the transmission state as long as the vehicle 181 is not traveling, a feeling of oppression is felt rather than the road wall fixed in the light shielding state. It is possible to realize road walls with less

<Example of configuration for realizing the light shielding device of FIGS. 16 and 17>
Next, with reference to the block diagram of FIG. 18, the detailed configuration for realizing the light shielding device of FIGS. 16 and 17 will be described. In addition, about the light-shielding wall 11 which comprises a road wall, and the camera 12, since it is the same as the function demonstrated with reference to FIG. 1 thru | or 3, the description shall be abbreviate | omitted suitably. Further, in the configuration of FIG. 18, components having the same functions as those of the configuration of FIG. 5 have the same reference numerals and the same names, and the description thereof will be appropriately omitted.

  That is, the light blocking device in FIG. 18 differs from the light blocking device in FIG. 5 in that the vehicle position determining portion 191 and the light blocking transmitting position calculating portion 192 replace the acquired image determining portion 52 and the light blocking transmitting position calculating portion 53. It is a point provided.

  The vehicle position determination unit 191 identifies the position of the vehicle 181 on the road 171 based on the depth image captured by the camera 12 provided along the central separator of the road 171 and supplied from the image acquisition unit 51. Then, based on the information of the specified position of the vehicle 181, it is determined whether or not there is a vehicle 181 whose occupancy area 172 can be seen from the passenger, and the determination result is supplied to the light shielding transmission position calculation unit 192. At this time, when there is a vehicle 181 from which the passenger can see the living area 172, the vehicle position determination unit 191 also supplies information on the position of the vehicle 181 to the light shielding transmission position calculation unit 192.

  When the light shielding transmission position calculation unit 192 acquires information on the detected position of the vehicle 181 together with the determination result indicating that the vehicle is detected, a light shielding wall existing in a range where the occupant area 172 can be seen by the passenger of the vehicle 181 The light shielding transmission information for controlling the 11 panels 21 in the light shielding state and controlling the other panels 21 in the transmission state is generated and stored in the light shielding transmission storage unit 54. That is, the road wall consisting of the light shielding wall 11 is normally controlled to be in the transmission state, and in the state as it is, from the passenger of the vehicle 181 traveling on the road 171 through the road wall consisting of the light shielding wall 11 in the transmission state The interior of the dwelling area 172 is visible. Therefore, when a vehicle 181 on which a passenger capable of visually recognizing the living area 172 is detected is detected, when the vehicle 181 passes, a panel of the light shielding wall 11 in an area where the occupant can visually recognize the living area 172 21 is controlled to be in the light blocking state, and the other panels 21 are controlled to be in the transmitting state.

  With such a configuration, in the light blocking wall 11 as a road wall, the panel 21 in a range in which the passenger area can be seen by the passenger is controlled to be in a light shielding state among the vehicles 181 passing through the road. It is possible to protect the privacy of In addition, when there is no vehicle 181 on the road 171 where the occupant can see the living area 172 from the passenger, all panels 21 of the light shielding wall 11 as the road wall are controlled to be in a transparent state. On the other hand, it is possible to realize a road wall that does not give an unnecessary sense of oppression such as the view on the road 171 side can not be seen.

<The road wall blinding process by the shading device of FIG. 18>
Next, the road wall blinding process in the control unit 13 of the light shielding device in FIG. 18 will be described with reference to the flowchart in FIG.

  In step S <b> 101, the camera 12 provided along the road 171 takes an image of the road 171 as a depth image and supplies the image to the image acquisition unit 51.

  In step S102, the image acquisition unit 51 supplies the depth image supplied from the camera 12 to the vehicle position determination unit 191.

  In step S103, the vehicle position determination unit 191 determines the presence or absence of the vehicle 181 that travels on the road 171 by the depth image and whose occupancy area 172 can be viewed by the passenger.

  More specifically, the vehicle position determination unit 191 detects the vehicle 181 from the depth image captured by the camera 12, and when the vehicle 181 is detected, further identifies and identifies the passenger of the detected vehicle 181. The line of sight of the passenger is estimated, and the presence or absence of the vehicle 181 in which the passenger in a state where the living area 172 can be seen is aboard is determined. Note that, when the vehicle 181 is not detected, the vehicle position determination unit 191 determines that there is no vehicle 181 in a state in which the occupancy area 172 can be seen by the passenger.

  If it is determined in step S103 that there is a vehicle 181 in which the occupant can see the living area 172, the process proceeds to step S104.

  In step S104, the vehicle position determination unit 191 determines the position with respect to the road wall formed of the light shielding wall 11 from the position in the depth image of the vehicle 181 in a state where the occupancy area 172 can be seen by the passenger. An area where the area 172 can be seen is determined and stored in the light shielding transmission position calculation unit 192.

  In step S105, the light shielding transmission position calculation unit 192 sets any unprocessed region in the predetermined region set in units of panels 21 in the light shielding wall 11 constituting the road wall as the process management region.

  In step S106, the light blocking transmission position calculation unit 192 determines whether the position of the panel 21 in the processing target area is a position near the area of the living area 172 seen by the passenger. If it is determined in step S105 that the position of the panel 21 in the processing target area is a position near the area where the passenger area of the vehicle traveling on the road 171 can see the living area 172, the process proceeds to step S107.

  In step S107, the light shielding transmission position calculation unit 192 stores the light shielding transmission information in the light shielding transmission storage unit 54 as controlling the panel 21 in the processing target region to the light shielding state. In accordance with this process, the light shielding transmission control unit 55 controls the panel 21 in the processing target area to the light shielding state based on the light shielding transmission information stored in the light shielding transmission storage unit 54.

  On the other hand, if it is determined in step S106 that the position of the panel 21 in the processing target area is not a position near the area where the occupant of the vehicle traveling on the road 171 sees the living area 172, the process proceeds to step S108. move on.

  In step S108, the light shielding transmission position calculation unit 192 stores the light shielding transmission information in the light shielding transmission storage unit 54 as controlling the panel 21 in the processing target region into the transmission state. In accordance with this process, the light shielding transmission control unit 55 controls the panel 21 in the processing target area to the light transmitting state based on the light shielding transmission information stored in the light shielding transmission storage unit 54.

  In step S109, the light shielding transmission position calculation unit 192 determines whether or not there is an unprocessed area in the area of the panel 21 in the light shielding wall 11. If there is an unprocessed area, the process is It returns to S105. That is, the processes of steps S105 to S109 are repeated until there is no unprocessed area. Then, when it is determined in step S109 that there is no unprocessed area, the process proceeds to step S110. If it is determined in step S103 that there is no vehicle 181 in which the occupant can see the living area 172 from the passenger, the processing in steps S104 to S109 is skipped.

  In step S110, the vehicle position determination unit 191 determines whether or not the end of the process is instructed. If the end is not instructed, the process returns to step S101, and the subsequent processes are repeated. Then, in step S110, when it is determined that the end is instructed, the process ends.

  That is, as shown in FIG. 16 and FIG. 17 by the above processing, it is a vehicle 181 traveling on the road 171, which is opposite to the road 171 across the road wall consisting of the light shielding wall 11 from the passenger. The vehicle 108 in which the living area 172 can be seen is detected, and the panel 21 in the area where the living area 172 can be seen from the passenger of the vehicle 181 in the light shielding wall 11 is controlled to the light shielding state, and the other panels 21 are It is controlled to the transparent state.

  As a result, in the light shielding wall 11 as the road wall, the panel 21 in the area where the passenger area can be seen from the passenger is controlled to be light shielding in the light shielding wall 11 as the road wall by the above-described processing. It is possible to protect the privacy of residents of In addition, when there is no vehicle 181 on the road 171 where the occupant can see the living area 172 from the passenger, all panels 21 of the light shielding wall 11 as the road wall are controlled to be in a transparent state. It is possible to realize a road wall that does not give an unnecessary sense of oppression. Furthermore, in the area along the road 171 where the living area 172 does not exist, all the panels 21 of the light shielding wall 11 as the road wall are in the transmission state, so the passenger of the vehicle 181 travels openly. It becomes possible to get a sense. Also, depending on the situation where the vehicle 181 passes through the road 171, for example, when the residential area 172 exists along the road 171, when the vehicle 181 is traveling at a speed lower than the speed limit, Since the living area 172 can be easily recognized by the occupant, the panel 21 of the light shielding wall 11 which is a road wall may be controlled to be in the light shielding state, and in this way, priority is given to privacy protection. It becomes possible. On the other hand, even when the residence area 172 exists along the road 171, when the vehicle 181 is traveling at the speed limit or more, it is difficult for the occupant of the vehicle 181 to visually recognize the residence area 172. The panel 21 of the light shielding wall 11 may be controlled to be in the transmission state, and by doing this, the road wall having a sense of opening to the occupants of the living area and the It becomes possible to realize.
